Testosterone is a male sex hormone that plays a vital role in the development of male reproductive tissues such as the testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle mass, body hair growth and a deeper voice. Testosterone is also important for maintaining bone density, red blood cell production and overall well-being.
Testosterone levels naturally decrease with age, but low levels can also be caused by certain medical conditions or injuries. Symptoms of low testosterone may include fatigue, decreased sex drive, erectile dysfunction, and decreased muscle mass. Testosterone replacement therapy is a common treatment for low testosterone. However, testosterone replacement therapy can have potential side effects and should only be considered after a thorough evaluation of the individual’s medical history and testosterone levels by a healthcare professional.
